## Customer Reviews

### ⭐⭐⭐⭐⭐ Miata NB1 to NB2 Headlight Conversion
*by P***Z on April 17, 2025*

I did a headlight conversion from a Mazda Miata NB1 to NB2 and used this wiring harness. The NB1 Miata has a ground switching circuit, so the diode in the harness needs to be removed. Once that's done, the low beams stay on when I turn on the high beams. The indicator on the dash also works.I wouldn't say this is super amazing quality, but it gets the job done and has been working so far, so I recommend the product!

### ⭐⭐⭐⭐ Does the job with a tweak.
*by N***L on January 3, 2023*

Converting my NB1 Mazda Miata to NB2 head lights. Wire lengths were perfect for this application. Had high and low beams always on until I cut diode out of the harness where it plugs into the stock head light plug. I think this is because the miata had a common voltage and switched ground, but I'm not sure. Lows stay on with high beam, but high beams cut off when switched to low. I don't seem to have a high beam indicator on my dash. I'll keep tweaking it to see if I can get that to work.

### ⭐⭐⭐⭐⭐ Nice
*by J***R on June 15, 2021*

Nice and easy to install
